FOLDING-MACHINE ATTACHMENT.

Application filed, May 3,

To all. whom it may concern:

Be it known that I, JOHN BERNARD HAG- man, a citizen of the United States, residing. .at lVappingers Falls, county of Dutchess,-State of New York, have invented a new and useful Folding-Machine. Attachment,.of which the following is a specification.-

My invention relates-to an attachment for machinesused for the purpose of folding cloth or fabrics,- such as cotton fabrics. Someof the-objects. of my invention are to providemeans .whereby cloth folding machinesmay be used for folding doubled cloth to provide means for passing the doubled clothfrom a source. of supply, such as a roll orpile to the folding mechanism in such manner as to prevent creasing of the cloth; and also to provide means whereby this is, done so efficiently that the amount of cloth folded in a given time may be considerably greater than has been possible by means of prior arrangements.

A further object of my invention is to provide folding means for doubled cloth, which shall obviate thewiring now required.

The preferred form of'apparatus according to my invention is illustrated in the drawing,.iin which Figu're'l is an end elevation of such apparatus, part of-the cloth being torn away and other parts being broken away for the sake of clarity;

Figure 2 is. a side elevation looking from the right in Figure 1; and

Figure 3 is a cross-section of the guide member .13, on the line a-a of Figure 2.

Similar numerals refer to similar parts in both of the views.

According to the preferred form of my invention, a roll of doubled cloth 1 is placed ini'the bracket 2..in such 1 manner as to be free to revolve therein. The edge of the cloth... which; isfolded-y is placed toward as left llor. at. the backof Fig, .2.

.Abovettherdll-bfelbth a p a i-r of rp ower nip; rolls r3,- 4 which draw the cloth from the roll 1 and dropit into the curved, hanging. pan fn as at 6. This panbe. madeof sheet or other material lth atlwill not stain the cloth. The speed of the rolls 3,

is-..controlled so that there is always .a surplusyofzcloth .lying .in the :p an .5; the purpose of-.'this is-to' furnish an ample supply of cloth for the-intermittent pull of the 1 ing.;.niechani sm.

Upon, leaving the pan 5, the cloth passes". over an elevated platform 7, placed above... the frame 8 of the folding machine The platforin'r may be made. of'wood or,otheif. rigid. material and is provided with an upstanding flange 9 whichis placed at the left; of the platform when viewed as inFig, 1;; the. folded edge of the, cloth, as it passes over} the platform, is guided by this flangel. Leaving the platform 7, the, cloth passesjbe tween pr ght uppo s-1.0, 'lQaacl over.- idle roll. 11, placed in the, vertical plane, of the mid-point of travel of the hooker blade of he folding mechanism,. nd'abQYe-ls h mechanism.

The pull on the cloth exerted by the hooker blade of the folding mechanism is intermittent and jerky; therefore, means must be provided to insure the cloths being delivered to the hooker blade free from creases. Such means, in the preferred form shown, consist of the platform 7, Which. operates to smooth out the cloth as it is pulled out of the pan 5, this operation be ing assisted by the weight of the cloth. hanging from the edge of the pan; further, the idle roll 11 and the cooperating Weight 12, by virtue of pressure on the cloth as it passes over the roll, hold the same under sufficient tension to prevent the cloths becoming slack or over-running itself; lastly, any inequalities at the fold side of the cloth are evened out by. means of the beveled edge 15 of the guide member 13.

I recognize that various modifications in detail and in arrangement of parts of my apparatus may be made by those skilled in the art without departing from the scope of my invention, and I therefore desire protection for all such modifications as come within the scope of the appended claims.

It will be evident also that according to my invention all necessity for wiring is done away with.

Having described the preferred form of my invention what I claim is:
